ASSEMBLY and INSTALLATION. Re: Figs 1 & 2 On receipt inspect the machine to ensure that all parts are accounted for and that no damage was incurred during transit. Any deficiency or damage should be reported to your CLARKE dealer immediately. The main body of the saw is fully assembled and adjusted at the factory. It is necessary only to fit the accessories supplied as follows: Fig.3 1. 2. 3. 4. 5. 6. 7. Mount the machine on a firm solid base that will not move under load.
OPERATION. A. Cross Cutting (at 90O) Ref: Figs 1 & 2 First, set the work in place. Clamp it firmly against the table and back fence. Check the security of the Bevel Locking Knob (N) and tighten if necessary, also ensure the table is locked using the Table Locking Knob (D). NOTE: If the workpiece is not entirely straight, ensure that the portion at either side of the intended cut rests firmly against the table and back fence.
C. Straight Bevel Cutting As with Mitre Cutting, this is a cross cutting operation, except that the blade is not perpendicular to the table (see illustration) Fig.6 Ensure the table is set so that the table pointer lines up with the zero on the scale on the bed. Slacken off the Bevel Locking Knob (N), and swing the Head to the side. Set the head to the required angle according to the scale (M). Lock the head in position by retightening the Bevel Locking Knob.
MAINTENANCE 1. General User maintenance is limited to changing the saw blade when necessary, renewing the motors’ carbon brushes, maintaining adjustments, and ensuring that after use, any sawdust or wood chips are cleaned away, with a low pressure air line or brush, paying particular attention to the motor air vents which should be kept clear at all times.
Fig.11 4. Remove the screw securing the upper plastic guard, arrowed in Fig.11, and pull away the guard. 5. Unscrew and remove the Blade securing screw using the claw and box spanners provided, taking great care to avoid damaging your hand on the saw blade teeth. Fig.12 IMPORTANT: The securing screw has a LEFT HAND THREAD, i.e. turn it CLOCKWISE to undo. Fig.13 6. Remove the outer flange followed by the blade. If necessary give the blade a gentle tap to dislodge it from the inner flange. 7.
3. Renewing Motor Brushes Eventually, the motors’ carbon brushes will need replacing. This task may be carried out quickly and easily as follows. 1. Remove the two cross head screws, securing the motors’ end cover, and pull off the cover. 2. Disconnect the spade connector, shown in Fig. 15, then pull out the brush carrier, complete with brush, as shown in Fig. 14. Fig.14 The cable is located on a plastic peg, shown in Fig. 15 and will simply pull away as you remove the brush. 4.
ADJUSTMENTS Ref: Fig 16 It may be necessary from time to time, to check various settings and make appropriate adjustments. a. Squareness of Blade It is most important to check that the blade is exactly perpendicular to the table. To do this, place a small square on Fig.16 the table and bring it up to the blade, checking to see if it is square.
